1.GABAA Receptors in Neuropsychiatric Disorders and Its Therapeutic Potential
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(10):2236-2241
Abundant evidences indicate a role of GABAergic system in the pathogenesis of neuropsychiatric dis-orders. GABAA receptors modulators have been long used in clinical. But the unwanted side-effect and risk of drug dependence have limited their use. With the increase understanding of the role of individual GABAA recep-tor subtypes in the pathology of these diseases, the subtype-selective GABAA receptors modulators and the multi-compound therapy may serve as potential therapeutic strategies. Here we review the researches which revealed the involvement of GABAA receptors in anxiety, depression and schizophrenia, and the research for new development in subtype-selective GABAA receptor modulators.

OBJECTIVEThis longitudinal study aimed to investigate the caries status of primary and permanent teeth among 6-year-old children in Sichuan Province from 2010 to 2012.
METHODSA sample that comprised 652 6-year-old children from six different elementary schools (three represented the urban areas, and the other three represented the rural areas) were examined according to a baseline, with follow-up examinations at 1, 2, and 3 years. Eruption and caries experience were re- corded using World Health Organization criteria.
RESULTSThe prevalence rates of primary tooth caries of 6-year-old children in Sichuan Province for 3 years were 74.23% (484/652), 75.61% (493/652), and 81.90% (534/652). The filling rate of the primary teeth was 5.87% (145/2,471) in 2012, with significant differences (P < 0.01) between the urban areas [10.84% (133/ 1,227)] and rural areas [0.96% (12/1,244)]. The total pit and fissure rate of the first molar was 14.11% (92/652) in 2012, with significant differences between the two areas (P < 0.01) [rural: 0.66% (2/303); urban: 25.79% (90/349)].
CONCLUSIONThe pre- valence of caries in the primary and permanent teeth of 6-year-old children was high. An increasing prevalence tendency was observed as the age increased. The prevalence of first molar caries indicated that prevention and control of dental caries should be performed as early as possible.

Objective To investigate the clinical efficiency of repairing ankle and calf wounds by antegrade or retrograde perforating flap of posterior tibial artery. Methods 13 cases with skin defects of ankle and calf wounds were reviewd. The defects were repaired using antegrade or retrograde perforating flap of posterior tibial artery from January 2011 to February 2013, 8 males and 5 females; aged 19 to 65 years old. Wounds were located in the ankle and calf, area which the tibial artery support contu-sioned slightly;defects were associated with exposed bone or tendon, exposed blood vessels. Of the 13 cases, 5 cases have multiple ankle fracture with blood circulation disorders, internal and external fracture fixation were performed emergency with blood ves-sels and nerves exposed, at the same time emergency line wound repair by posterior tibial artery perforating flap. The other 8 cases have no blood vessels and nerves exposure, and accepted vacuum sealing drainage emergency external fixation and flap surgery. Seven cases accepted V-Y antegrade perforating flap of posterior tibial artery, 6 cases using retrograde tibial artery perforator flap. Whose defects were ranged from 1.5 cm×2.0 cm to 9.0 cm×5.0 cm. Antegrade or retrograde perforating flap of posterior tibial ar-tery with 1.5 cm×3.0 cm to 14.0 cm×7.0 cm was used to repair ankle or lower leg medial defect. Antegrade flap donor site sutured directly, but retrograde flap donor site take full thickness skin graft repair from abdomen. Results Circulations of the all 13 cases were stable, with wound healing well after 2 weeks. The patients were followed up for 6 months to 24 months, average of 13 months. All flap graft survived, pedicle no bloated andcat eardeformity. Flaps were soft, no bloated appearance;color was con-sistent with normal skin. Fracture line in the 5 patients was disappeared. Bone healing time was 3.0 to 4.0 months. At the direct su-ture skin donor sites, postoperative scar was small;skin graft donor sites had no obvious scar. Postoperative ankle dorsiflexion 10° to 25°, plantar flexion 15° to 45°. Patients were extremely satisfied with the results of repair. Conclusion Using antegrade or ret-rograde posterior tibial artery perforator flap without sacrificing the main vessel, it is a simple and effective method to repair the medial malleolus and calf wounds.

AIM:To discuss the related factors that affected the stability of posterior corneal surface after laser in situ keratomileusis ( LASIK) .
METHODS:About 64 patients (64 eyes) were enrolled. The correlation among the changes in posterior corneal surface 6 month after LASIK, surgery method, corneal flap thickness ( FT ) , ablation thickness ( AT ) , postoperative residual corneal stroma thickness ( RCST ) , preoperative thinnest corneal thickness ( CT ) , flap thickness/preoperative thinnest corneal thickness ( FT/CT ) , ablation thickness/preoperative thinnest corneal thickness ( AT/CT) , postoperative residual corneal stroma thickness/preoperative thinnest corneal thickness ( RCST/CT) , anterior and posterior preoperative corneal height, the difference of the forward shift in posterior corneal surface ( diff value ) of preoperative and preoperative intraocular pressure were analyzed.
RESULTS: The changes of diff value between preoperative and postoperative were related with diopter (r=0.419, P=0.014), AT (r=0.394, P=0.023), AT/CT (r=0.501, P=0.004), Diff value of preoperative (r=0.501, P=0. 004), RCST (r=-0. 385, P=0. 033) and RCST/CT (r=-0. 401, P=0. 025). The changes of height value from posterior corneal surface between preoperative and postoperative were related with diopter (r=0. 520, P=0. 002), AT (r=0.504, P=0. 003), AT/CT (r=0. 442, P=0. 013), Diff value of preoperative (r=0. 624, P=0. 000) and RCST/CT (r=-0. 394, P=0. 028).
CONCLUSION: AT, RCST, AT/CT, RCST/CT and diff value of preoperative should be the key index that predicted the stability of posterior corneal surface after LASIK,the further research will give the range of safety value.
